Parvati was a good social player during her season and is still doing a good job, but she may have overplayed her hand. Amanda is key to her plan and she is pissed off at Parvati making promises for her without her consent.
The previews seems to indicate that Ozzy is on the winning team for the RC, but loses the IC.
I don't feel sorry for Eliza at all. She isn't shy or socially ackward. She said herself that it's her fault no one liked her.
I agree that Jason was stupid (1) for believing the HII was real (2) offering it to Eliza (3) bragging after winning ONE IIC. By offering it to Eliza it would have backdoored Ozzy, but it wouldn't have gotten him any closer to winning.
